The correct answer is: A - troponin, C - actin
Actin : Protein that makes up most of the thin myofilaments in a sarcomere muscle fiber.

Troponin : Regulatory protein that binds to actin, tropomyosin, and calcium.

Tropomyosin : Regulatory protein that covers myosin-binding sites to prevent actin from binding to myosin.
